SYLVANIA, ASSIGNORS TO- sAID PHILIPs.

MACH INE FOR MANUFACTURING ELECTRIC CABLES.

SPECIFICATION forming part of Letters Patent No. 275,408, dated April10, 1883.

Application filed October 5, 1882. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM J. PHILIPs and GEORGE L, KITSON, citizensof the Unit- 1 ed States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsyl- Vania, have invented certain new anduseful Improvements in Machines for Manufacturing Electric Gables, ofwhich the following is a specification, reference being had therein tothe accompanying drawings, wherein-- Figure 1 is a longitudinal verticalsection, partly in elevation, of a machine embodying our. invention.Fig. 2 is a detail section, and Fig. 3 is a detail plan.

Our invention has relation to machines for manufacturing electric cablesor conductors, being especially adapted for that class of cables whereinthe wire or conductor is incased in cement or a plastic composition andsur- 2o rounded with a metallic'sheathing, and has for its object toprovide a machine wherein such cables may be easily and expeditiouslymade at a slight cost.

Our invention accordingly consists of the novel construction,combination, and arrangement of parts as hereinafter set forth andclaimed.

Referring to the accompanying drawings, A

"represents the frame of the machine, upon 0 which are convenientlyplaced in suitable relation toeach other a reel of wire, B, and a reelof sheet-lead, G, in the form of a long strip or a ribbon.

D represents a die having a tapering open- 3 5 ing, d, held in a frame,E, which is composed of a stationary section, 6, and a removablesection,e, connected to each other by bolts 6 F represents a mandrel hinged orpivoted -at f to bars or arms f, secured to the frame E 0 in anysuitable manner. Said mandrel is thereby so placed that its end f iscentrally located within the opening d of die D, and it is formed withpassages or openings f and f which leadinto each other at f The end f ofthe mandrel is formed with a taper, as shown in Fig. 2.

V G represents a tank or reservoir designed to hold rosin or othermaterial, which is melted by steam entering the jacket 9 from pipe g.

The reservoir G is connected to passage f of the mandrel by a pipe, H,having cock -h.

Said pipe is surrounded by a steam-jacket, h,

to keep the rosin in a fluid condition as it passes from reservoir G tomandrel F. Said jacket has a petcock, h for drawing off the water ofcondensation.

I represents another die,loeated back of die I), and is secured inaframe, E, of a-c'onstruction corresponding to that of frame E; and K isa reel for the finished cable.

The operation is as follows: Steam is admitted through pipe 9 to jacketsg and h to melt the rosin in reservoir G. The lead strip 0 is passedaround or beneath the mandrel F and through die-opening 6?, while thewire 13 is conducted through the mandrel-openingfi. I As the lead stripO is drawn through opening ditis folded together to form a tube, whichincloses the wire B. The cock h being opened,

the melted rosin flows from reservoir G through pipe H to passage 1,thence to passage f around the wire B, filling up the space between saidwire and the tube formed by the folding of strip 0, as plainlyillustrated in Fig. 2, to form a'cable, w. (Shown. in Fig. 1.) In thepassage of the cable from dies D to I the rosin therein cools andcontracts to leave a space between it and the lead casing; but as thelatter passes through the die I it is thereby further folded or forceddown on said rosin to So take up such space, and when the joint y insaid casing is soldered or lead-burned the cable is finished and woundupon the reel K. When the latter is full the cable is out, whereuponsaid reel is removed and is ready for 8 transportation, a new reel beingsubstituted for the one removed, and the operation continued.

It will be seen that the die I is merelyafinishing-die to set the leaddown upon the cooled 0 T0811].

The soldering of thejointin the tube or casing may be done by handbefore the same is drawn through die I, and before it is wound on thereel K; or, if desired, any suitable mechanism may be interposed toeffect such result or to lead-burn such joint. 4

The wire B may be a plain wire or consist of a wire covered with pitchand a coveringof asbestus,-as described in an application filed by usSeptember 27 1882.

' ,We have shown and described the application of steam for melting therosin in reservoir G but, if desired, gas, oil, or other heating mediamaybe substituted therefor. So, too, we have shown the rosin as passingby gravity to mandrel F, and being forced into and around the passage f3 by its hydrostatic pressure; but. if desired, a weight or plunger maybe placed in reservoir G to accomplish such end, or a pump may besubstituted therefor. By the use of the foregoing-described means we areable to rapidly and cheaply manufacture electric cables of any desireddiameter and length. 7

We have described the reservoir G as being used to hold the rosin andmelt it therein but we do not confine ourselves to the use of rosin, aspitch or other like substance may be placed therein. Where more than onewireis placed in the cable the mandrel and die openings are enlarged toprovide ample room for the passage therethrough of the different wiresfrom their respective reels.

The mandrel F, being hinged or pivoted, is free to yield to accommodateitself to any irregularities in the wire fed therethrough hence allfriction between the mandrel and wire and chafing ofthe insulationofthelatter is avoided.

What we claim as our invention is- 1. In a machine for making electriccables, the combination of a die, a mandrel, a reservoir, a reel oflead, and a reel of wire, substantially as shown and described.

2. In a machine for manufacturing electric cables, a die, a mandrel, areservoir, and means for heating the same, and a reel of lead and ofwire, substantially as shown and described.

3. In an organized machine for manufacturing cables for electricity, adie having a taperin g opening, a mandrel with correspondinglyshapedend, a reservoir and means for heating the same, and a reel ofsheet-lead and of wire, substantially as shown and described.

4.. The combination of die D, mandrel F, having tapered end f andpassages f f pipe H, reservoir Gr, with heating means, and a reel ofwire, B, and of sheet-lead, G, substantially as shown and described.

5. In combination with the die D, having tapered opening d, the mandrelF, with conical end f and passages f f", substantially as shown anddescribed.

6. In combination with the die D, having opening d, the mandrel F,hinged at f, and constructed substantiallyas shown and described.

7. In a machine for making electric cables, the combination of aforming-die, a finishingdie, a mandrel, a reservoir with heating means,and a reel of wire and of sheet-lead, substantially as shown anddescribed.

8. In an organized machine for makingelectric cables, a die, a mandrel,a reservoir with heating means connected to said mandrel, afinishing-die, and bearings for supporting the wire and casing for thecable,substantially as shown and described.

9. In an organized machine for making electric wires or cables, thecombination of a reel of sheet-lead, a reservoir for rosin or othernon-conductor, means for heating and liquefying such non-conductor, areel of wire or cable, and a die having a tapering opening with a pipeor connection communicating with said reservoir,substantially as shownand described.

In testimony whereof we aifix our signatures in presence of twowitnesses.
